Metabolic Transformations in the Area of Municipal Solid Waste Management in Russian Megalopolises: The City of Moscow Case

Received 15 June 2022. Accepted 23 December 2022. Published online 30 December 2022.Based on secondary data analysis and semi-structured expert interviews (n = 90), the study analyses metabolic transformations in the area of municipal solid waste (MSW) management in Russian megalopolises using the city of Moscow as a case study. The findings suggest that the key node that triggered numerous interdependent processes involved the changes introduced in the legislation on MSW management and the decision to shut down several large MSW landfills without the simultaneous implementation of other landfills. These actions affected the health of the population and contributed to environmental inequality. The authors provide recommendations for the mitigation of risks associated with MSW generation, recycling, and storage in large Russian cities.The research was supported by the Russian Science Foundation under Grant No. 22-28-00392 “Waste production and disposal in the megalopolises of Russia: multisectoral and interdisciplinary analysis”

Sustainable Energy Transition in Russia and Ghana Within a Multi-Level Perspective

Received 5 April 2023. Accepted 30 August 2023. Published online 6 October 2023.This paper is a case study based on a critical review of existing literature and primary data through interviews to investigate energy transition framing and manifestation in the Global South. It provides critical insights into sustainable energy transition in Ghana and Russia within a multi-level perspective (MLP). We argue that whereas Ghana’s energy transition concepts and policies are mirrored by landscape, regime, and niche, practical transitioning has been slow due to inadequate resources and incentives, limited historical culpability in global greenhouse gas, and the country being locked-in to existing hydrocarbon socio-technical systems. The MLP approach is useful in describing energy technologies, markets, and consumption practices. But in Russia, social policy at distinct levels is united by centralised energy law and technical systems, as well as institutional rules and differences based on costs in economic regions. This paper contributes to the energy transitioning discourse within the Global South using Russia and Ghana as cases to highlight how transition policies and practices differ from country to country, driven by economic, political, social, cultural, and historical elements with global frameworks serving as guides. Rigid application of landscape, regime, and niche concepts is challenged in describing and analysing the context-specific nuances in sustainable energy transition policy across spaces. There is a fundamental challenge of mechanically fusing a one-fits-all approach to sustainable energy transitioning in developing countries and societies due to differences in historical contributions to climatic issues and inequality of access to resources and technologies. Energy transition processes and practices should be compatible with social justice.The fieldwork and data analysis for the Russian case was supported by the Russian Science Foundation under Grant No. 22-28-00392 “Waste production and disposal in the megalopolises of Russia: multisectoral and interdisciplinary analysis”.

Current perspectives on social mapping of urban territories

© 2015 Canadian Center of Science and Education. All rights reserved. The article provides insights on the conceptualization of social mapping and its three main types: statistical, anthropological and network-oriented. Each perspective is described in detail and illustrated by examples. Artificial Neuron Networks with a particular interest to self-organizing maps are embedded in the analysis as a cutting-edge technique of social mapping now actively used by interdisciplinary researchers. The authors argue that despite the variety of social mapping techniques, they all have common features such as ordering and grouping of objects based on particular framework and empirical data, flexibility, visibility, citizens’ engagement on developing maps. Along with advantages, authors acknowledge such limitations of social mapping as data exclusion, data scale incompatibility and complexity of datasets that are beyond the cognitive abilities of the analyst

Differential diagnosis of amiodarone-induced thyrotoxicosis in a patient with atrial fibrillation and agranulocytosis on the background of thyrostatic therapy. Case report

Atrial fibrillation is the most common heart rhythm disorder in patients with chronic heart failure. One of the most effective antiarrhythmic drugs for the treatment and prevention of a wide range of supraventricular and ventricular tachyarrhythmia is amiodarone. In the group of patients with paroxysmal atrial fibrillation and low left ventricular ejection fraction, it is the drug of choice when conducting a „rhythm control“ strategy. Patients receiving amiodarone often develop an adverse event – amiodarone-induced thyrotoxicosis, which exacerbates the course of cardiovascular pathology. In this article, we consider a clinical case of amiodarone-induced thyrotoxicosis in a 30-year-old patient with dilated cardiomyopathy and agranulocytosis that developed against the background of thyrostatic therapy

Magnetic force microscope tip-induced remagnetization of CoPt nanodisks with perpendicular anisotropy

We report on the results of a magnetic force microscopy investigation of remagnetization processes in arrays of CoPt nanodisks with diameters of 35 and 200 nm and a thickness of 9.8 nm fabricated by e-beam lithography and ion etching. The controllable magnetization reversal of individual CoPt nanodisks by the magnetic force microscope (MFM) tip-induced magnetic field was demonstrated. We observed experimentally two essentially different processes of tip-induced remagnetization. Magnetization reversal of 200 nm disks was observed when the probe moved across the particle while in case of 35 nm nanodisks one-touch remagnetization was realized. Micromagnetic modeling based on the Landau-Lifshitz-Gilbert (LLG) equation demonstrated that the tip-induced magnetization reversal occurs through the essentially inhomogeneous states. Computer simulations confirmed that in case of 200 nm disks the mechanism of embryo nucleation with reversed magnetization and further dynamic propagation following the probe moving across the particle was realized. On the other hand one-touch remagnetization of 35 nm disks occurs through the inhomogeneous vortexlike state. Micromagnetic LLG simulations showed that magnetization reversal in an inhomogeneous MFM probe field has a lower energy barrier in comparison with the mechanism of coherent rotation, which takes place in a homogeneous external magnetic field

TNF-induced necroptosis in L929 cells is tightly regulated by multiple TNFR1 complex I and II members

TNF receptor 1 signaling induces NF-κB activation and necroptosis in L929 cells. We previously reported that cellular inhibitor of apoptosis protein-mediated receptor-interacting protein 1 (RIP1) ubiquitination acts as a cytoprotective mechanism, whereas knockdown of cylindromatosis, a RIP1-deubiquitinating enzyme, protects against tumor necrosis factor (TNF)-induced necroptosis. We report here that RIP1 is a crucial mediator of canonical NF-κB activation in L929 cells, therefore questioning the relative cytoprotective contribution of RIP1 ubiquitination versus canonical NF-κB activation. We found that attenuated NF-κB activation has no impact on TNF-induced necroptosis. However, we identified A20 and linear ubiquitin chain assembly complex as negative regulators of necroptosis. Unexpectedly, and in contrast to RIP3, we also found that knockdown of RIP1 did not block TNF cytotoxicity. Cell death typing revealed that RIP1-depleted cells switch from necroptotic to apoptotic death, indicating that RIP1 can also suppress apoptosis in L929 cells. Inversely, we observed that Fas-associated protein via a death domain, cellular FLICE inhibitory protein and caspase-8, which are all involved in the initiation of apoptosis, counteract necroptosis induction. Finally, we also report RIP1-independent but RIP3-mediated necroptosis in the context of TNF signaling in particular conditions

Genome-wide inference of regulatory networks in Streptomyces coelicolor

Background: The onset of antibiotics production in Streptomyces species is co-ordinated with differentiation events. An understanding of the genetic circuits that regulate these coupled biological phenomena is essential to discover and engineer the pharmacologically important natural products made by these species. The availability of genomic tools and access to a large warehouse of transcriptome data for the model organism, Streptomyces coelicolor, provides incentive to decipher the intricacies of the regulatory cascades and develop biologically meaningful hypotheses. Results: In this study, more than 500 samples of genome-wide temporal transcriptome data, comprising wild-type and more than 25 regulatory gene mutants of Streptomyces coelicolor probed across multiple stress and medium conditions, were investigated. Information based on transcript and functional similarity was used to update a previously-predicted whole-genome operon map and further applied to predict transcriptional networks constituting modules enriched in diverse functions such as secondary metabolism, and sigma factor. The predicted network displays a scale-free architecture with a small-world property observed in many biological networks. The networks were further investigated to identify functionally-relevant modules that exhibit functional coherence and a consensus motif in the promoter elements indicative of DNA-binding elements. Conclusions: Despite the enormous experimental as well as computational challenges, a systems approach for integrating diverse genome-scale datasets to elucidate complex regulatory networks is beginning to emerge. We present an integrated analysis of transcriptome data and genomic features to refine a whole-genome operon map and to construct regulatory networks at the cistron level in Streptomyces coelicolor. The functionally-relevant modules identified in this study pose as potential targets for further studies and verification.

The invertebrate lysozyme effector ILYS-3 is systemically activated in response to danger signals and confers antimicrobial protection in C. elegans

Little is known about the relative contributions and importance of antibacterial effectors in the nematode C. elegans, despite extensive work on the innate immune responses in this organism. We report an investigation of the expression, function and regulation of the six ilys (invertebrate-type lysozyme) genes of C. elegans. These genes exhibited a surprising variety of tissue-specific expression patterns and responses to starvation or bacterial infection. The most strongly expressed, ilys-3, was investigated in detail. ILYS-3 protein was expressed constitutively in the pharynx and coelomocytes, and dynamically in the intestine. Analysis of mutants showed that ILYS-3 was required for pharyngeal grinding (disruption of bacterial cells) during normal growth and consequently it contributes to longevity, as well as being protective against bacterial pathogens. Both starvation and challenge with Gram-positive pathogens resulted in ERK-MAPK-dependent up-regulation of ilys-3 in the intestine. The intestinal induction by pathogens, but not starvation, was found to be dependent on MPK-1 activity in the pharynx rather than in the intestine, demonstrating unexpected communication between these two tissues. The coelomocyte expression appeared to contribute little to normal growth or immunity. Recombinant ILYS-3 protein was found to exhibit appropriate lytic activity against Gram-positive cell wall material
